My Omron Hem 637 wrist rocket sits on the right hand side of my desk, well within reach. Older unit that has worked well for me for a long time. Just keep the battery changed regularly and it's not far off any of the Doc's Office readings.
I go by a very irregular schedule of checking the BP..but trust this one to tattletale me into hitting the pill bottle when I get too busy to remember to keep on the regular schedules with the magic pills. 4 Stents and a near miss'll do that for you.
